Marc,

Your VCR responds to NEC2:128.123 (repeating NEC protocol device 128 sub-device 123). Power toggle is command or function 19.

Here are some other commands that I am fairly certain that your device will respond to. The gaps in the numbers will likely have other commands with similar functions (16, 17, 20 would be my first guesses for a discrete power command):

CMD Function
000 num 0
001 num 1
002 num 2
003 num 3
004 num 4
005 num 5
006 num 6
007 num 7
008 num 8
009 num 9
010 channel up
011 channel down

013 timer
015 channel >100


018 tv/vcr
019 power

021 record
022 play
023 stop
024 fast fwd
025 rewind
026 pause

030 tape speed
041 minute advance
042 hour advance
065 up arrow
066 down arrow
067 Arrow RIGHT(Alt)
068 Arrow LEFT(Alt)
069 enter
074 channel
075 counter memory
076 counter
078 eject
080 menu
086 program guide
103 Arrow RIGHT
104 Arrow LEFT
239 input toggle

The best Hex Generator for this is probably John Fine's MakeHex that is in files under utilities.

Once you download it open the NEC2.irp file below:
***************************************************
Device=5.5
Function=0..255

Protocol=NEC2 'Like NEC, but repeats entire pattern
Frequency=38000
Time Base=564
One=1,-3
Zero=1,-1
Prefix=8,-8
Suffix=1,-84
*************************************************

Change it to Device=128.123

and Change F= to the range of commands or functions that you want it to generate. It is probably set as below to the default that will give all 256.

F=0..255

(F=20..20 will just give command 20)

In windows explorer Drag the edited NEC2.irp and drop it on MakeHex.exe and you get a text file NEC2.txt with your commands.


HTH & GL,

Jon
